As data and identity theft becomes more and more common, the market is growing for biometric（生物测量）technologies—like fingerprint scans—to keep others out of private e-spaces. At present, these technologies are still expensive, though.

Researchers from Georgia Tech say that they have come up with a low-cost device（装置）that gets around this problem: a smart keyboard. This smart keyboard precisely measures the cadence（节奏）with which one types and the pressure fingers apply to each key. The keyboard could offer a strong layer of security by analyzing things like the force of a user’s typing and the time between key presses. These patterns are unique to each person. Thus, the keyboard can determine people’s identities, and by extension, whether they should be given access to the computer it’s connected to—regardless of whether someone gets the password right.

It also doesn’t require a new type of technology that people aren’t already familiar with. Everybody uses a keyboard and everybody types differently.

In a study describing the technology, the researchers had 100 volunteers type the word “touch”four times using the smart keyboard. Data collected from the device could be used to recognize different participants based on how they typed, with very low error rates. The researchers say that the keyboard should be pretty straightforward to commercialize and is mostly made of inexpensive, plastic-like parts. The team hopes to make it to market in the near future.

【翻译】随着数据和身份盗窃越来越普遍，市场对指纹扫描等生物识别技术的需求也与日俱增，以防他人侵犯私人电子空间。不过，目前这些技术的价格均十分高昂。

【翻译】佐治亚理工学院的研究人员称，他们已经发明了一种低成本的设备——智能键盘,来破解这一难题。这款智能键盘可以精确测量人们打字的节奏，以及手指施加在每个按键的力度。通过分析用户打字的力度和敲击按键的间隔时间，该键盘就能给用户提供一道强有力的安全防护。由于这些模式对每个人来说都是独一无二的，因此，键盘可以确定人们的身份，并进而决定是否允许他们访问与之相连的计算机——不管其有正确的密码与否。

【翻译】它也无需什么人们不熟悉的新技术。每个人都使用键盘，每个人的打字方式也都与众不同。（这就够了。）

【翻译】在一项介绍该技术的研究中，研究人员让100名志愿者用这款智能键盘输入“touch”这个词四次。键盘便能利用其所收集的数据、基于不同参与者的打字方式对他们加以识别，其错误率非常之低。研究人员说，该键盘应该很容易商业化，因为其主要是由廉价的塑料部件制成。该团队希望在不久的将来将其推向市场。
